摘　　要：目的:探讨无症状低钾血症患者心电图改变与低钾的关系。方法:诊断为低钾血症230例,其中无症状低钾血症60例用ECG变化归类分析。60例低钾血症患者ECG阳性45例(75.0%)例明显高于ECG阴性15例(25.0%)(X^2=3.845,P<0.05);中度低钾与轻度低钾比较,无显著性差异(X^2=0.539,P>0.05);重度低钾与中度低钾比较,有显著性差异(X^2=4.111,P>0.05);重度低钾与轻度低钾比较,有显著性差异(X^2=3.928,P<0.05)。结论:心电图的改变对无症状低钾血症患者的诊断更具有优势。Objective To investigate the relationship between electxocardiogram （ECG） change and hypokalemia in Asymptomatic hypokalemia. Method 230 cases with hypokalemia, including 60 cases of asymptomatic hypokalemia and analyzed with the ECG changes. Results 60 cases with Asymptomatic hypokalemia ,45cases （75.0%）with ECG-positive were significantly heighter than that 15 cases （25.0%） with ECG negative （X2=3.845,P〈0.05）;moderate hypokalemia compared with mild hypokalemia, were no significant difference （x2=0.539,P〉0.05）;severe hypokalemia compared with moderate hypokalemia,there was significant difference （X2=4.111,P〉0.05）; severe hypokalemia compared with mild hypokalemia, significant difference（x2=3.928, P〈0.05）, Conclusions ECG changes on the diagnosis of asymptomatic hypokalemia are more advantages.
